I'm not an employee of Shapeways by any means. As for approval of our designs, I can't say there was much of any process in place after the launch. By the time I got around to submitting a 2nd design, most my initial contacts involved had moved on to other things. I was then forwarded to those that were currently in charge, but most my questions about the state of SFA, where new artists can apply, submission process, all were skipped.
If you were already an artist, you had one big advantage to the approval process, your personal SFA store. Just like the account I'm using right now, we can log into our store and upload and order new designs on our own. That's what I did with my 2nd design, Rarity, and my quest for approval. I uploaded it, made it public, but not for sale, and ordered a personal copy for myself for printability verification, plus I wanted a copy
. Then I started asking around about approval. When I finally was put in touch with those currently in charge, instead of answering my questions, they diverted my order to ship to Hasbro for photographs. They didn't explain if photos were required, if they were going to then ship the model to me after, or if not, who pays for it. Later a Shapeways employees finally gave me credit because I never got answers from Hasbro.
Then my 2nd quest started to get Rarity added to the MLP section next to my other print. Until they did, no one would know it's there unless they click on my first design and see related prints or visit my store. After months it was never done. At one point a Shapeways employee requested it to be done and to remind him after week if it didn't happen. I sent the reminder and never heard back.
Basically, it seemed like the whole process for SFA slowly fell apart until finally that February email that pretty much put everything on hold until they relaunched with a bigger and better SFA.
